get_standard_colormap/[2,3]

     get_standard_colormap(+Name, -Colormap)
     get_standard_colormap(+Screen, +Name, -Colormap)
     

Colormap is a standard colormap on Screen that you may use, and that may be shared with other applications running on the same screen. Name is the name of a standard colormap. Screen defaults to the default screen.

These procedures rely on another program, usually the window manager, to actually create the standard colormaps. If your window manager doesn't do this, then these procedures will report an error.
